the modules to be reversed, thereby putting eth0 and eth1 on different NICs,
it was a holiday weekend, and I was not able to get anyone at Digium until
Tuesday. They still would not permit the relicensing. We ended up three days
without the codecs we paid for, and so I had to re-engineer the system,
moving the phones to uLaw and using gsm at both ends of the trunk. For
reliability reasons I would not advise g729. If you lose a NIC, or you are
using the motherboard's interface and it fails, you will have to relicense.
If that fails, you have to restructure everything.</FONT></SPAN></DIV>

<BLOCKQUOTE type="cite"><PRE wrap="">I think you are at least morally correct, I think I might do that.
However, I guess part fo the question is, does it make much difference, am I
that badly off without G729?
The other point it, doesn't Digium realize they are pissing customers off
with their attitude? I took a lot of my time to explain my situation, send
them a letter, call several times, and they still won't allow me to use what
I paid for. Is it my fault they have a stupid and unworkable enforcement
system? Is it more important to prevent piracy or keep customers? I think
they have it backwards.

They're also really bad about supporting the activation of the codecs
when you do buy them...I bought 6 of them (3 for each site in this
case), and tried to activate them through the customer's very
restrictive firewall. Of course it didn't work since the firewall
doesn't allow arbitrary port numbers to leave the network, and they
have never even returned my calls on the issue. It wouldn't really
bother me as much if they'd at least have had the courtesy to call me
and tell me it was not possible to activate them over some other
method (manual, http, https, etc). I've still got all 6 of them
completely unused because of that. I'm now very selective on when and
if I'll use g.729. My advice is to use anything else first, and use
g.729 as a last resort.
